Easiest Way to Check a Relay

In this video I'll show you the easiest way to check a relay on your vehicle. Its the old switcharoo method. You just take a like relay that should be available in your fuse box and swap it with the relay you suspect is bad. If the component that the relay controls then starts to work then you most probably have a bad relay. In my opinion, this is the first thing you should do after checking fuses when diagnosing certain electrical problems.

Note: Try to swap relays that are not related to each other. If you swap a suspect relay with the PCM or Main Power relay then chances are the relay you are trying to check may cause other things not to work, including the relay you swapped. Also, only swap relays that are identical. Make sure they have the same number of terminals, are the same color, are the same brand, and have the same part number. If you are not sure if two relays are interchangeable then contact your parts store to verify.

Also, if you are not familiar with relays you should educate your self. If you are not sure what a relay is, what they look like or how they function then I would not suggest using this information. Swapping a relay with a part that is not a relay can cause damage to your vehicle, so make sure you know what parts you are handling before you do this.
